Flexible interfaces support a wider variety of application needs—SerDes, fiber for long distances or additional 10/100/1000TX ports. Provides the most cost effective Gigabit conectivity to the desktop for all remote, branch, and home office needs. 802.1Q tag VLAN, trunking, and 802.1p priority enables the switch to be designed into a wide variety of applications from unmanaged to smart switch. CPUs are not required to initialize and run in costsensitive unmanaged applications, providing true Plug and Play connectivity. Internal oscillator circuit simplifies design and reduces overall system cost. Ability to gather and support basic management statistics with only a very low cost microcontroller. Low-cost management using the on-chip MIB registers allows the collection and transmission of statistics for each port and allows an upward migration path for corporate users. On-chip HP auto-MDI/MDIX on all tranceivers automatically detects and corrects for crossover cables and allows direct switch-to-switch connection.

It combines all the functions of a high-speed switch system, including packet buffer, PHY transceivers, media access controllers, address management, and a nonblocking switch fabric into a single 0.13 µm CMOS device. It complies with IEEE 802.3, 802.3u, 802.3ab 802.3x specifications, including the MAC control, pause frame, and auto-negotiation subsections, providing compatibility with all industry-standard Ethernet, Fast Ethernet, and Gigabit Ethernet devices. This device contains eight full-duplex 10BASE-T/100BASE-TX Fast Ethernet transceivers and one 10/100/1000BASE-T transceiver, each of which performs all of the physical layer interface functions for 10BASE-T Ethernet on Category 3, 4, or 5 unshielded twisted-pair (UTP) cable and 100BASE-TX Fast Ethernet on Category 5 UTP cable. SPI or EEPROM interfaces provide easy programming of the 802.1p QoS. This allows switch traffic to be given different classes of priority or service—for example, voice traffic for IP phone applications, video traffic for multimedia applications, or data traffic for e-mail applications. Up to 4,000 VLANs can be set up via the SPI port. Even though this device is primarily targeted for the costsensitive unmanaged market, very low cost management can LED Interface LEDs also be provided using the proprietary MIB Autocast™ function. MIB Autocast encapsulates the on-chip MIB statistics and sends them out automatically on a predefined port (or ports) at programmed intervals. This feature is part of the 8051 micro smart switch option for basic "smart management" via a console port. As part of the "smart switch" mode, the BCM5382M periodically transmits Ethernet frames on a designated port. The frames can be intercepted by an external management probe or a dedicated network management application, resident on any node within the network. In addition, the ROBOSmartswitchTM software provides system and port configuration, VLAN and QoS set up, and IGMP snooping. The BCM5382M designed to work in unmanaged stand-alone or managed mode via the on-chip MII interface to an ARM7 CPU. This provides support for the Ethernet-like MIB, bridge MIB, layer 2 management functions, private MIB, MIB II and 4 groups of RMON. ROBO-managed LinuxTM software also supports RTOS, BSP and loader, SNMP agent, console, WEB UI, spanning tree, Tenet UI, port mirroring, trunking and easy programming of VLAN groups, QoS priorities and IGMP snooping.
